The Alabama State product already has shown he has a gun for an arm. If he proves he is a quick study when it comes to the West Coast offense, Jackson could slide into the No. 2 role behind Brad Johnson sooner rather than later. As of Wednesday morning, however, Jackson remained one of two Vikings rookies unsigned.
That, however, can be quickly forgotten if Taylor proves he's ready to become a starting running back in the NFL. Taylor has spent his career behind Jamal Lewis in Baltimore, so the 26-year old does not have much wear and tear on his body.
If Taylor can move into the No. 1 role, the oft-injured Mewelde Moore can be used as a backup and also handle the duties as the lead punt and kick returner.
No doubt he will be monitored closely.
A healthy Birk will be crucial on a line that figures to have one of the best left sides in the NFL. Steve Hutchinson, who signed a seven-year, $49 million free-agent deal to leave Seattle, will be the left guard and Bryant McKinnie returns at left tackle. Birk figures to be the line's anchor, as he was before 2005.
But Greenway will get every chance to show he is ready to be a starter in the NFL. If this proves to be the case, he could take over on the weak side, enabling Henderson to slide to the middle.
Napoleon Harris and Dontarrious Thomas figure to get early looks for the starting job in the middle, but Henderson could be the best fit long term.
But the talkative corner seems determined to forget his first season in Minnesota and has added about 15 pounds to his 5-11 frame in an effort to get ready to play the Tampa-2 defense that new defensive coordinator Mike Tomlin has brought with him from the Buccaneers.
The early portion of camp figures to provide a good indication if the extra weight will help Smoot stay healthy and be more physical (the goal) or if it will slow him down (not so good).
